Improved shoe-edge-burnishing machine



UNITED STATES PATENT OEEICE..

IMPROVED SHOE-EDGE-BURNISHING MACHINE.

Specification forming part of Letters Patent No. 50,856, dated November7, 1865.

To all rwhom it may concern:

Be it known that I, NATHANIEL S. THOMP- SON, of Stoneharn, in the countyot' Middlesex and State of Massachusetts, have invented an Improvementin Machines for Burnishing the Edges of Boots and Shoes; and I do herebydeclare that the following is a full and exact description thereof,reference being had to the accompanying drawings, and to the letters ofreference marked thereon.

The nature of myinvcntion consists in cornbining and arranging aburnishing-wheel, of iron or any other suitable metal, with a movableadjustable guide in such a manner that the whole shall form a machine bywhich the edge ot' a heel, or thick or thin sole of a boot or shoe, maybe burnished as Well as the same is done by hand, and much more rapidly.

To enable others skilled in the art to make and use my invention, l willproceed to describe its construction and operation.

In the drawings, Figure l is an isometrical view of the machine entire.Fig. 2 is a plan showing the lever L and slide G, upon which is fastenedthe guide F, the whole showing in what manner the guide F is adjusted bythe lever L.

A A represent the stand or table upon which the machine is fastened.

B B are housings in which the shaft C runs.

E represents the burnishingwheel, which is made fast to the shaft C.

F is a movable guide attached to the slide G, and operated by the leverL, (shown more fullyin Fig. 2.) The guideis held in any desired positionby means ot' the set-screw S.

I have tried many methods for arranging a movable guide or itsequivalent. For instance, the guide may be a collar around theburnishing-wheel, movable by means ot' a screw or le ver, or the guideitself may be stationary, and the burnishing-wheel may be made to slidein and out. These methods are all good, but the one that I have adoptedin my model is one ot' the cheapest, and is, perhaps, as good as anyequivalent mechanical expedient.

In operating this machine it is simply necessary to adj ust the guide tothe point required by the thickness ot' the edge of the sole or heel tobe burnished, and to hold the edge ot' the slice tirmly and steadilyagainst the burnishing-wheel, moving the shoe along as the edge becomesburnished.

What I claim as my invention, and desire to secure by Letters Patent ot'the United States, 1s

The combination ot' the adjustable-guide F with the burnishing-wheel E,or the mechanical equivalent of such combination, substantially as andfor the purpose specified.
